You guys may remember my attempt at putting a BMW throttle body on a Super Six manifold. Well, after somebody asked if it would take boost and I realized it wouldn't, I decided to bite the bullet and have a machine shop do things right. It cost me $600, but it's done now!

The setup uses Supra Turbo injectors and a Ford 4.6 throttle body on a Clifford manifold. The fuel rail is made from square extruded aluminum tubing with a 3/8" pipe thread at each end. You can see the picture here:

Matt your set up is really cool.


I have a ford throttle body that i removed from a lincoln towncar.

it is used and anyone can have it for $10 plus cost to ship it.

Yeowza... $600!

I don't know if you saw my thread a few weeks ago, Clifford sold me a manifold with the bosses already drilled out for $289, and a fuel rail for $20. The fuel rail was an oem type, just a tube with injector bungs welded on it and hose barbs on each end of it.

The only manufacutring I had to do was the hold downs, and that consisted of a strip of aluminum bent at 45 degrees with 2 holes drilled into it, similar to the ones you have. Also had to make an adapter ofr throttle body out of some aluminum plate. I'll post an updated picture in this thread too if you'd like.

Wait, does that $600 include machineing, injector, and manifold cost?

I hadn't known about the Clifford setup when I sent this out, unfortunately. If I had, I'd have gone that route, if it would have worked with the Nippondenso injectors. The $600 included all the machine work, including the adapter and making a fuel rail from scratch, but I paid about $150 for the rest (injectors, throttle body, manifold, all bought used) and will need to spend a bit more to get the injectors cleaned.

Nice work, Matt. Keep us updated on the install progress. That's a fair price for that work. The Clifford deal is a heckuva steal for anyone still looking.

You can clean injectors yourself if you want.... you neeed to run a solvent, perhaps thinner, or carb cleaner, through it in reverse to backflush the crud out the input side so it won't clog the tiny holes intended to deliver the fuel.

Use your efi pump (it can be a low pressure one you don't need a high pressure one for cleaning purposes), secure a hose to the output side of the injector with a hose clamp, and pulse the injectors to 12v once the pump is running. You'll need some sort of basin to hold the liquid....

Also read http://www.slantsix.org/articles/dibias ... ersion.htm thats Bob's article about his efi install and shows how he cleaned his wrecking yard injectors. Again, I'd attach the hose to the bottom end of the injectors so they are backflushed.

I opted to buy new injectors from www.fiveomotorsports.com and pay for new ones instead of hassling with used ones. Check out www.rceng.com if you want them cleaned by a shop.

VERY nice! I'd love to go this route if we're able to EFI my girl's Dart. What ECU do you plan on using?

Also, as far as cleaning injectors, I agree with Pierre about sending them to RC Engineering. Just send 'em eight or nine and ask for the six best matched injectors to be sent back. I'll be doing that with my truck hopefully soon after I return home. From what I've been told, it's WELL worth the money and makes a huge difference in how smoothly the engine runs.
